My A30 died and replaced it with the A30.5. It works great and now my altitude is dead on.

I forgot to mention that the A30.5 was a direct replacement for my dead A30 mod3.

I bought a new ACK A-30.5 yesterday, I bought it to replace my older ACK A-30. I checked the pins and I have power at pin 8 and ground on pin 15 So I plugged it in hooked up to the old pitostatic and tested it. It tested perfectly! So it was basically plug-and-play. Could not have been easier, if ACK has worked for the last 30 years on my plane it will work for the next 30 years.

I have an SL70 UPS Aviation transponder that can digitally read out altitude that it is transmitting to ATC. Will this encoder provide that capability to the transponder display?
Per Garmin the ACK encoder with give the SL 70 altitude information on the display.
Is the ACK A-30.5 encoder compatible with the Becker BXP 6401-2-(01) transponder?
Yes, the ACK A-30.5 is compatible.
Is the ACK A-30.5 compatible with the Becker ATC 4401 transponder?
Yes the ACK A-30.5 will work with the Becker transponder.
Is the ACK A-30 compatible with Narco AT50A TSO transponder? What else is in the box?
Yes, the ACK can work with the Narco AT 50A. In the manual shows the wire diagram. In the box is a 4 foot harness, 4 foot pitot-static line, installation hardware and the installation manual.
Will the ACK-30.5 Altitude Encoder work with a king KT76A?
Per the manual for the ACK-30.5 Altitude Encoder, they do give the wiring diagram for the King KT76A.
Is the ACK A-30.5 encoder compatible with the KT76C transponder?
Per the Manual, The ACK A-30.5 is compatible with the KT76C.
I have an Ack 30. Will this replace it without a harness change?
Per the Manual, The Ack 30.5 is plug compatible with all earlier Ack 30 models.
Is the ACK A30.5 compatible to the Garmin GTX 328?
Yes, the A30.5 is compatible with the GTX 328.
Is the ACK A-30.5 altitude encoder compatible with Garmin 155XL?
Yes, they are compatible.
Is the ACK A-30.5 compatible with GARMIN GTX 335 transponder?
Yes, this will work with the Garmin GTX 335. Garmin also makes an encoder which plugs into the back of the transponder, which can be found under part number 11-14162.
Is the ACK A-30.5 encoder compatible with Garmin GTX 327?
Yes the ACK A-30.5 encoder is compatible with the Garmin GTX 327.
Is the ACK A-30.5 encoder compatible with Microair t2000 transponder?
Yes, per the operation/installation manual it compatible with the Microair T2000.
What does back shell mean in wiring your A30 unit, ground?
The 15 pin connector with harness that comes with the unit.
Is this encoder compatible with Garmin GTX 330? Does it meet mode s altitude requirements?
Yes, it is compatible with the 330. Yes, this encoder meets the requirements for a mode s transponder.
Is the ACK A30.5 altitude encoder compatible to the Garmin GTX 320?
Yes, this is compatible with the Garmin GTX 320.
I know the ACK A-30.5 is compatible with the STRATUS ESG Transponder as far as transponder requirements go. But! Is it compatible with all the requirements of the associated GRAY CODES for ADS-B Out or the transponder? The ACK A-30.5 is a Parallel output device.
Every transponder requires an altitude encoder. The altitude encoder does not play a part in meeting the ADSB mandate.
To meet the mandate, you must have an ADS-out transponder paired with a certified WAAS GPS antenna.
Does the ACK 30.5 work with the Narco AT150 TSO transponder?
Yes, per the manufacturer the ACK A-30.5 will work with your Narco At150.
Does the ACK A-30.5 encoder have to be calibrated after you get it or does the encoder come calibrated and you just need to plug the wiring harness into the encoder?
The AC 30.5 comes calibrated and just needs to be plugged in to work properly.
